This is an automated review by Codex GPT-5.6 Luna(Max).

Compatibility analysis

SAFE. The complete published AWS SDK Java v2 sequence from 2.55.1 through 2.55.4 was reviewed in ROUND_1, including every transition and the target release. No Druid-used API or ABI removal, runtime incompatibility, configuration change, serialization or wire-format change, persistence impact, client incompatibility, transitive dependency conflict, license issue, or extension/plugin SPI change was found.

Druid impact

The PR changes the root AWS SDK version property from 2.55.1 to 2.55.4. Druid’s existing S3, Kinesis, EC2, RDS, and common AWS call sites use APIs that remain compatible. The bounded follow-up repair aligns the AWS SDK license metadata to 2.55.4; no Java source or Druid SPI was changed.

Validation

The pushed head is 37a81b8, based on 1319898. The license metadata parses successfully, git diff --check passes, and the worktree is clean. The original packaging-check failure was diagnosed as stale PR-caused license metadata and was repaired in the pushed commit.

CI gate

Fresh exact-head validation reports 27 of 27 CheckRuns COMPLETED/SUCCESS, zero StatusContexts, and no failure, neutral, or pending result. The PR is OPEN, non-draft, MERGEABLE, and CLEAN. No CI rerun was needed.

Automation actions

I submitted an APPROVED review for the exact current head above. No merge was performed.
